HENRY J. BRUGGEMAN, OF SIOUX CITY, IOWA.

FOLDING PASTEBOARD TRAY.

resents.

To all whom it may concern Be it known that I, HENRY J. Brusse- MAN,citizen of the United States, residing at Sioux City, in the county ofWoodbury and State of Iowa, have invented certain new and usefulImprovements in Folding Pasteboard Trays; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in collapsible card board candytrays such as are used in packing candy and other articles easilymashed, and an object of the invention is to provide a tray of thischaracter struck from one piece of material and having an upturned rimformed of individual members having novel locking means for securing theends together.

A further object of the invention is to provide a tray, the upstandingrim of which is provided with means for locking in place the partingstrips which serve to divide the tray into compartments.

A still further object of the invention is to provide a tray blank withrim flaps, the ends of which may be inturned to hold parting strips andin further providing looking tabs or flaps integral with the blank andadapted to fold over to lock the ends of the rim flaps and hold the samesecurely to the parting strip.

A still further object of the invention is to provide a candy trayhaving novel looking means in conjunction with the rim, this means beingso formed as to transmit the pressure from superimposed trays directlyto the trays beneath without in any way deforming the rims of lockingmembers.

With these and other objects in view the invention comprises certainnovel construction, combinations, and arrangements of parts as will behereinafter more fully described and claimed.

In the accompanying drawings, wherein corresponding parts are designatedby like reference characters, Figure 1 shows the blank from which thetray is formed, Fig. 2 is a perspective view looking into the top of thetray, Fig. 3 is a fragmental view of one of the locking members halfclosed, Fig. f is a view similar to Fig. 3 with the looking devicesclosed, Fig. 5 is a vertical section taken through the center of thetray and showing one of the locking devices, and Fig.

6 is a vertical section taken on lines-6-6 of Fig. i and looking in thedirection of the arrows. Fig. 7 is a perspective view of a portion ofthe tray showing inbent tabs in place for the reception of one end ofthe parting strip.

Heretofore, it has been proposed to use trays of the same generalcharacter that disclosed herein for the purpose of packing candy orsimilar foods, the boxes in most instances being formed from a singleblank and then a simple parting strip inserted but not held in place byany means integral with the tray. 1 am aware that it has been proposedto use boxes or trays of this general type wherein the parting stripsare formed integral with the tray, but such parts require specialmachines for providing these parting strips, and also said parting strps are usually double'and therefore re quire twice the amount ofmaterial actually required for the purpose of separating the tray intocompartments.

My present invention aims to provide a s mple tray readily assembledwherein the rim is formed of flaps having inwardly ex tending tabsadapted to be held together by flaps formed integral with the body ofthe tray and in placing between the tabs parting strips which will notonly be held in place by the tabs but will also serve to cooperate withthe means for locking the rim in place and for holding the rim moresecurely. In order to explain more fully the tray, reference may be madeto the drawings and the following description, where the invention hasbeen shown as applied to a circular tray, although it is to beunderstood that the tray may be oval, rectilinear, or in fact, anygeometrical form which may be used for purposes of packing.

In the drawings, 1 designates the blank which, as shown in Fig. 1 iscircular and has extending from four sides thereof rim flaps 2, thesides of these flaps being substantially at right angles when the blankis out. Any number of these rim flaps could be used, but insomuch as incommon practice it is suflicient to divide the tray into fourcompartments, it will be suilicient to provide four of these rim flaps.The ends of each of these rim flaps are provided with a tab 3 and thereand the main part of the tlap a line of scoring 3;, which may be giventhe blank when the latter is cut from the sheet material, which may becardboard or any other suitable material having the necessary rigidityfor sustaining the weight or" the contents of the trays. The lines ofscoring 4 are not continuous but there is formed between the oppositeedges of the flap 2 and in line of said scorings slits 5, the purpose ofwhich will appear hereinafter. As shown in the blank, each of the endsof the several rim flaps is provided with slots 6 and 7 located upon theupper and lower edges of saidrim flaps respectively when the tray isassembled.

Extending radially from the blank 1 and lying between the adjacent endsof rim flaps are looking flaps 8 each of which is provided with a lineof scoring 9 between the flap and the blank, while there is provided anadditional line of scoring 10 which is sub stantially parallel to thescorings 9, or it the scorings are made curved, they will be concentric.As in the case of the scoring at, the

scoring 10 is not continuous but is interrupted by the slit 11 formed ineach of the flaps 8, said slit 11 being substantially double the lengthof the distance between the scoring 1 and the shoulder 12 formed by theslot 6 and the rim flap 2. Extending centrally from the slit 11 andradial with respect to the blank is an incision 1-3, the upper end ofwhich is enlar ed so as to form a slot- 14, while the inner end isenlarged to form a slot 15, which communicates with the slit 11. Theseslots 1e and 15 define tongues 16 and 17 of such length as to fit snuglyinto the slits 5. The line of scoring 10 taken with the incision 13defines a part of tabs 18 and 19 which are secured to the radial flaps8.

The portions of the material which lie between the tabs 3 and the tabs18 and 19, such as are indicated at 20 are removed, and an incision 1formed in the blank for separating the tabs 3. Also, the parts of thematerial from which the blank is out which lies between the body 1, therim flap and the radial flaps are also removed, these portions beingindicated at 22, while there is provided an incision 23 which separatesthe tabs 18 and 19 from the rim flaps 2 and their corresponding tabs 3.As shown in the drawings, when the portions 22 are removed, the inneredges 24: oi the rim flaps are extended somewhat so that as the traysassemble, said edge 24 will extend below the top surface of the body 1and rest directly upon the surface upon which the whole tray issupported. This edge 2% is separated from the slot 7 by means of ashoulder 25, which is so related with respect to the body 1 that whenthe tray is assembled, said shoulder will engage the parts of the radialflaps indicated at .16.

Tn order LO assemble the tray, the rim flaps 2 are each bent upwardlyalong the line or scoring 27 until the same are substantially at rightangles to the plane body 1. The flaps 3 are then bent inwardly along thelines of scoring 4, after which the ends of the rim flaps 2 are broughtin to conform to the gen eral outline of the finished tray. The lines ofscoring d in the rim flaps 2 are so po-si tioned that when the saidflaps 2 are made to conform to the shape of the tray, the tabs 3 willjust touch and will lie adjacent each other in parallel planes. Thisposition of the tabs 3 is indicated in dot and dash lines in Fig. 1,whereas the lines of scoring are made dotted to differentiate same fromthe lines showing position of the assembled rim flaps. In this position,the slits 5 are opposite each other and lie adjacent the rim of thetray. The radial flaps 8 then bent upwardly along the line of scoring 9,after which they are further bentover the rim flaps 2 along the line ofscoring 10, this position being shown in Fig. 3. The tabs 18 and 19 arethen pushed dow iwardly to the position shown in Figs. 2 and 4-, whilethe tongues 16 and 17 respectively lie in the slits 5. By this means,the rim flaps 2 are locked by means of the projecting radial flaps 8 andthe tabs 18 and 19 and by reason of the tongues entering the slits Itwill also be noted that the portions of the upper edge of the rim flap 2which lie between the shoulder 12 and the line of scoring at are lockedin the slit 11 and that the edge 2% lies in the plane of the bottom oithe body 1. Further, the slot 6 is made of such depth that the bentportions of the radial flap 8 along the line or scoring 10 will besubstantially in line with the top edge of the rim flap 2, and by thesevarious means it will be seen that the pressure or" the super-imposedtrays will be transmitted directly to the lower trays without bucklingor bending of any part of the tray. The slots 1% and 15 are made of thewidth substantially double the thickness of the material from which thetray is cut so that when the tabs 3 are locked in the position shown inFig. e, the sides of t the slots 1% and 15 may lie against the tabs 3,the tongues 16 and 17 being thus deep enough to extend the full depth ofthe slits 5. In this way, the inwardly extending tabs 3 are securelylocked in place.

In order to pr vide means for dividing the assembled tray incompartments, there is provided the requisite number of parting strips28, two of these strips being shown in the drawing. These strips are ofthe proper height so that their upper edges lie in the plane of the topof the tray and they are made of a length suiiicient to extend betweenthe radial flaps 8 when the latter are assembled. It will be noted byreferring to the dotted-line position in Fig. 1, that when the partingstrips 28 are in place, the tabs 8 are spaced or separated a shortdistance, so that the tongues 16 and 17 of the tabs 18 and 19respectively are forced apart and are therefore bound to the partingstrips 28. No particular method is shown for crossing the partingstrips, insomuch as this feature forms no part of the present invention.

What I claim is:

1. A tray comprising a bottom, a multipart rim extending from the bodyportion and having integral portions formed on the ends of the parts andextending inwardly of the tray, and parting strips held by said inwardlyextending members.

2. A tray comprising a body port-ion, a multipart rim extending from thebody portion, adjacent ends of adjacent parts of the rim meeting andextending inwardly of the tray, and parting strips held by the ends ofsaid parts.

3. A tray comprising a body portion, a rim, tabs formed on the rimextending inwardly of the tray, parting strips held by said inwardlyextending tabs, and means integral with the body portion adapted to locksaid tabs against the parting strips.

4. A tray comprising a body portion, a multipart rim extendingtherefrom, the ends of the parts of the rim lying adjacent to oneanother, and means integral with the body portion adapted to fit overadjacent parts of the rim, and adapted to engage the ends of said partsfor locking the same.

5. A tray comprising a body portion, rim

flaps extending upwardly from said body portion, and having inwardlyextending ends provided with slits, flaps extending from the bodyportion and having tongues extending therefrom, said flaps adapted toextend over the ends of the rim flaps and have the tongues engage theslits.

6. A tray comprising a body portion, rim flaps extending upwardly fromthe body portion and having inwardly extending ends provided with slits,flaps extending from the body portion, said flaps embracing the ends,tongues extending from the flaps and entering the slits, and a partingstrip separating said ends and tongues.

7 A tray comprising a body portion, rim flaps extending upwardlytherefrom and having inwardly extending adjacent ends, flaps integralwith the body portion adapted to fit over the rim flaps and embrace theends, means for interlocking the latter mentioned flaps with the ends,and a parting strip adapted to separate said ends and interlockingflaps.

In testimony whereof I affix my signature in presence of two witnesses.
